Risk Factors for Temporomandibular Disorders (TMD)

A risk factor is something that increases your likelihood of getting a disease or condition.

It is possible to develop TMD with or without the risk factors listed below. However, the more risk factors you have, the greater your likelihood of developing TMD. If you have a number of risk factors, ask your doctor what you can do to reduce your risk.

Risk factors for TMD include:

Stress-related Habits

Some of the stress-related habits that may increase your risk of TMD include:

Habitually clenching and unclenching your jaw

Biting your lip

Grinding your teeth during the day and/or at night in your sleep

Constantly or very regularly chewing things, such as gum or ice, for long periods of time
